I'm fine if the government mandates that they install their GPS tracker on my car in order for me to be legally allowed to drive it. The reason is because it's my decision to make; if I don't like the rules, I could just not drive. (And I don't like the rules for having a driver's license in Illinois, like "implied consent", so guess what, I don't drive or have a driver's license.)

I don't like being singled out for special treatment without some judicial oversight. That's the problem with the GPS trackers; the sneakiness of it. If it were done out in the open, then I wouldn't mind.
